More S1 upgrade kits please!!
you could feasibly use the C1 as a pair of upgrade kits, but its not ideal. Not sure why bitmain isnt selling upgrade kits for ~0.3BTC/kit
How many people would be interested in another S1 upgrade kit batch?
I want some, if the price is right.

I'd like 10 or 20 upgrade kits
HELP
Just received my Antminer S4 and having a difficult time setting it up. When turning the machine on it whirls at full speed/noise, but never settles down. The LCD screen is bright but never displays any text. Anyone know what the issue is?
This occurs whether directly plugged into my computer, or plugged into a Netgear N300 wifi to Ethernet adapter. I unscrewed the lid, and all of the cables appear to be plugged in properly.
Popped the SD Card out, and then pushed it back in. Miner worked! Stable after adding CK's cgminer mod. Running 1.82GH at (hopefully) 1060W as suggested on BtcGuild.

Congrats. The shipping gods have not been kind to S4s, although all three of mine worked out of the box. One had a bit of scratched paint.
Mind posting the Freq. and Voltage your using and/or a link to the article you read?

Okay I may grab one or two of these. I am interested in under clocked results.
so is anyone running freq 187.5 with 0.685 volts? if so what do you get for hash rate watts/ power numbers and fan speeds?
better yet has anyone done freq 175 with 0.670 volts? if so what do you get for hashrate watts used and fan speed?
TIA

Ask and yea shall receive (at least sometimes!): http://puu.sh/d3BqI/ad9aaf7d23.png - 187.5 at 0.685V.

I would love to see some again!
Those were a lot of fun. I'd be interested as well.

Do I think they are great investments no I don't.
But they may make money.
But they may make money.
I agree with "may" only because probability is not zero.
do they have special cables and connectors 
I get buy 3 s-4's with a coupon for 2762 if I down clock to 1800gh they burn 1100 watts so 5400 = 3300 watts this is .611 watts a gh
I'd like to see it. My first S4 worked for a long time with EVGA SUPERNOVA G2 1300W at frequency 181.25M and only 1630GH/s with 1180W
You can never from S4 .611 watts a gh
The second S4 is even more power hungry , at frequency 181.25M 1240W and 1800 GH/s
The second S4 PSU is without a PCI-E cables.

I've been running some numbers, one thing I see is that the SP-20 vs. the S4 is an under volt advantage that gains you money at the wall in favor of SP.. I may be wrong, but if they come out with new tech ANY batchs of the S4 won't even come close to ROI.. I bought some of the FIRST S4s to ship, and they are no where close to ROI . Even with the coupon, I can't pull the trigger when my first several S4's are so far under water. It takes me almost 15 days of mining to cover electricity cost alone. Anything after 15 days goes to the under water s4's .. This late in the game on the 28nm tech I can't find a reason to grab more. Anyone else have thoughts on how to make the s4 more profitable ?
With a coupon I can get 4 S4s for 3358 to my door. My calculations put me at Mid-February before i am losing money every day. All told I will spend $3358 and make about $1500 in revenue. So I lose $1800.
How is anyone buying these and making this work. Even with free power and difficulty increasing at 10% I don't break even until June of next year.
I would love to get into mining, but I cannot see how mining can make any sense to anyone anywhere unless you get the hardware for half what is the current going rate per mhs and free power.
2) most people mining assume the bitcoin price will rise such that profitability is extended
3) you can underclock/undervolt to 0.5w/GH to extend the lifespan
If you look at your calculations you basically assume it wont be profitable past june because you are assuming the price of bitcoin is still only $375 at that time, when (i personally believe) a price of $800+ is likely. If it isnt, you can expect the influx of new equipment to grind even further to a halt as all 1w/gh+ equipment is turned off.
I don't understand the price must rise to justify mining logic. I can spend 9 BTC on miners now, I don't care about the price in the future, i want my 9 BTC back. I will never get there with any calculation I come up with.
Anyone that is justifying buying a miner with a rising price, I suggest that you simply buy Bitcoin with your money rather than a stupid miner.
I would not be surprised to see a drop in hashrate and difficulty in the coming months. Which tells me the price is going down... not up.
why not ? do you pay high power? do you pay vat?
I get buy 3 s-4's with a coupon for 2762 if I down clock to 1800gh they burn 1100 watts so 5400 = 3300 watts this is .611 watts a gh
at 10 cents a watt and 3% diff jumps they break even in aug (btc stays at 375 usd)
if btc jumps to 400
they break even in June.
Do I think they are great investments no I don't.
But they may make money.

Looks like S4 is going EOL. Black friday deal posted on Saturday.
See bitmain sales announcement at the head (first post): 16 antminer S4 for ~13K with free shipping or ~$812 for 2Th.
Great price, but I have no use for 16 machines...
One machine is still ~$960 to US (with coupon that is expiring early tomorrow).

Exactly, coupon expires tomorrow, then free shipping on Dec 2. Marketing at it's best.
wait i want to make sure i understand this clearly?
So they are running coupon and after that expires they are moving into free shipping?
Are the Psu's still going up in flames?
1) https://bitcoinwisdom.com/bitcoin/difficulty difficulty is slowing, and its unlikely there will be any 10%+ increases until a dramatic price rise occurs - though next week may see a big jump due to the black friday deals by SPTech and Bitmain.

You can not underclock/undervolt Antminer S4 to 0.5w/GH
https://bitcointalksearch.org/topic/antminer-s4-discussion-and-support-thread-796839 clearly states that 500W/1000GH is the underclocking limit of the S4
